Professional Applications & Engineering Value
This M2.5 shoulder screw is engineered to address critical alignment and durability challenges in precision assemblies. The 18-8 stainless steel material provides excellent resistance to corrosion and oxidation, making it ideal for applications in electronics, machinery, and automotive sectors where environmental factors are a concern. The hex socket head design allows for compact installation in confined spaces, while the 15mm shoulder length with precise tolerances ensures accurate positioning of components like gears, bearings, and linkages. This reduces wear and misalignment, extending equipment life and minimizing maintenance downtime. The Class 6g thread and coarse pitch enhance reliability in high-vibration environments, offering a robust solution for industrial fastening needs.
Specification Summary & Compliance
This shoulder screw features a Metric M2.5x0.45mm thread with Class 6g tolerance for precise fit, a shoulder diameter of 3.5mm with tolerance from -0.025 to 0mm, and a shoulder length of 15mm with tolerance from 0 to 0.05mm. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to environmental and safety standards for industrial use.
